Referring to the accompanying drawings,

.my invention is shown in connection with a motor vehicle comprising achassis frame A supported on wheels B, an engine C supported on theforward end of said frame and having a driving shaft connection Sthrough housing D with the difhoused within the rear vehicle is providedwith the usual cab F for the driver, the usual lever G for manipulatingthe transmission gearmg 'ferential driving gear from the rear drivingaxle. The motor vehicle construction thus far described is well knownand it is considered unnecessary to il- Located back of the drivers cabF above the chassis frame A of the motor vehicle is a horizontal shaft1, which extends longitudinally of the vehicle at the longitudinalcenter 'line thereof and has its ends rotatably supported in bearings 2provided therefor on the upper ends of pedestals 3 rigidly secured tosald chassis frame. Located between the supporting pedestals 3 for theshaft 1 is a semi-cylindrical tank or container 4 adapted that is to betransported. The trough-like container 4 is and the usual clutch pedalfor con-. nectIng-the engine with and disconnecting it supported on saidshaft. The container is also supported intermediate its ends on a rollerearlng 5 journaled in a bracket 6 fixed to a cross member 8 whichextends from side rail to side rail of the chassis frame A of thevehicle. The right side wall of the container is 'provided, at a pointsubstantially midway of its length, with a laterally projectingdischarge spout or hopper 9 having converging side walls extending fromthe end of the container to the mouth of the discharge spout and havingits bottom inclined upwardly and outwardly from the lower portion ofsaid side wall of said container to the mouth of said discharge spout.This construction of rotary, right-hand, side delivery container permitsthe container to be readily discharge-d -or emptied by rotating it in adirection that will cause its discharge spout to swing downwardly into aposition which will permit the contents of the container to flowtherefrom by gravity; it also permits the quantity of concretedischarged from the container to be regulated by varying the angularposition of the discharge spout; and it also permits the concrete to bedischarged into a form while driving the vehicle along the side thereof,thereby securing an' even distribution of the concrete lengthwise of theform.

The left hand side of the container is weighted to cause the containerto return to its normal or upright position after bein rotated todischarge position; and the left rear corner of the container is,provided with a suitable stop 4 adapted to abut against the left siderail of the chassis frame and thus limit the return movement of saidcontainer. The container is rotated on its axis in a direction whichwill cause the discharge spout on the right side thereof to swingdownwardderv sides of the teeth of 1y to discharge its contents by meansof a cross shaft 10, which is journaled in bearings on the chassis frameA beneath the container and is provided at one end with a removablecrank 11, whereby said shaft may be manually rotated. The other end ofthe shaft 10 is provided with a worm 12 which meshes with a worm gear 13fixed to a shaft 14 having a pinion 15 fixed thereto which meshes withbottom of the container. worm gear 13 are The worm 12 and preferablylocated within a suitable housing '17 mounted on the chassis frame A.Mounted for vertical swinging movement on the left-hand side rail of thechassis frame opposite the arcuate rack 16 on the curved bottom of thecontainer is a pawl or ratchet 18 adapted to abut against the unsaidarcuate rack, said pawl 18 being held in engagement with said teeth bymeans of a coil spring 19. The

pawl 18 may be disengaged from"'thetee"h an arcuate rack 16 fixed to thecurved names? of the rack 16 on the bottom of the container by means ofa rock shaft 20 journaled on the left hand side rail of the chassisframe and provided at one end with a rock arm 20 adapted to bear againstthe inner face of said pawl. The other end of the rock arm is alsoprovided with a rock arm 20 which is actuated to rock the rock rodbymeans ofa push rod 21 which extends crosswise of the chassis framebeneath the container. when engaged with the rack 16 acts as a brake orcatch forpreventing the discharge side of the container from swingingupward, but said pawl does not interfere with the movement or saidcontainer to discharge position. The stop 4 on the container serves tolimit the return movement thereof to filling position; while movement ofsaid container to discharge position is prevented preferably by means ofa chain 22, one end of which is permanently secured to the bottom ofsaid container and the other end of which is de tachablysecured within anotch provided therefor in an upstanding bracket 23 secured to the rightside rail ofthe chassis frame The concrete mixture contained within thecontainer is continuously stirred or mixed. to preventseparation of thematerials or ingre-dients thereof from the time the mixture is placedwithin the container to the time of its discharge therefrom, by means ofa stirring device comprising two helically wound metal blades 24 mountedon the shaft 1 and rigidly secured thereto for rotation there- The pawl18 g with preferably by means of radial arms or spokes 1 fixed to saidshaft.

also serve as paddles for aiding the helical blades in stirring ormixing the concrete. As shown in the drawing the blade at one end of thetank is wound in the form of a left-hand helix and the blade at theother end is wound in the form of a right-hand helix, whereby the twoblades operate to force the concrete from the ends of the containertowards the middle thereof and thus operate to secure a complete discharge of the concrete from the container.

The stirring or mixing device is rotated within the container by meansof a suitable take-off box H attached to the transmission housing D andcontaining gears meshing with the continuous rotating gears of thetransmission gearing. A continuous rotating shaft 25 projects from thetake-oif box H and has a clutch connection 26 with a shaft 30 journaledin gearings provided therefor I on the inner face of the right side railof the chassis frame and having a gear '28 fixed thereto meshing with agear 29 fixed to the shaft 25. The clutch 26 is operated to connect theshaft 30 with the continuous rotat ing shaft 25 of the take-off boxby'means of a clutch shifter lever 31 operated by means of a'hand' lever82 fixed to a cross shaft 27, and which extends upwardly through thefloor boards of the cab within easy reach of the driver. The shaft 30which is rotatably supported on the right-hand side rail of the Ivehicle has a universal jointconnection 33with on a shaft 39-locatedthereabove.

1 a pinion 40 which ducing gear 41'fixed to one end of the shaft thetank by forcing it 1 of the stirring mechanism. By this arrangement thestirring device may be operated from the transmission gearing when thevehicle is in motion andwhen it is standing.

The hereinbefore described stirring or mixing device secures a thoroughand continuous mixing of the ingredients of the concrete in thecontainer by maintaining the ingredients i'n a state of continualagitation from the time the concrete is placed within the containeruntil it is discharged there from. The mixing device serves also tofacilitate the discharge of the concrete from towards the dischargespout thereof. The location of the discharge spout atthe side of thecontainer makes it easy to properly position the truck with reference tothe formsor wheelbarrows; and the rate of discharge of the concrete'fromthe tank may be varied, depending on angular position of the dischargespout, which is vice is simple and efficient and can be readilyprevented from returning to filling position by the pawl 18. The spoutis swung downwardly to obtain the desired rate .of flow of the concreteby means of the cross shaft 10 and is returned to its normal position byreleasing the pawl 18.

The driving mechanism for the stirring deconnected with the drivingmechanism of the vehicle to drive same when the vehicle is moving .orstanding by ,7 manipulating the clutch.

While I prefer to mix the concrete before placing, it in the containerof the motor vehicle for transport and to use the stirring device forpreventing separation of the ingredients of the concrete from the timethey are placed within the container until they ,are

dischargedtherefrom, it might be desirable, in some instances, to-placethe ingredients within the container before mixing and use the stirringdevice for initially mixing the ingredients and for maintaining suchmixture during transportation.
